MilTax is the Department of Defense's free tax service for the military community, run through Military OneSource. The MilTax software is built specifically for military life - deployments, combat pay, PCS moves and multi-state filings - and it is completely free: file your federal return and up to five state returns at no charge, with a 100% accuracy guarantee.
Prefer a human? MilTax consultants are available free by phone or chat for one-on-one help, and they are trained on military tax situations like the Military Spouses Residency Relief Act and moving deductions.
MilTax is free for active-duty service members, eligible family members and survivors, and for veterans and retirees up to 365 days after separation or retirement. The software opens each January for tax season (it returns in January 2027 for the next filing season), and eligibility is verified through DEERS.
